Injection device with dosage adjusting device with end position blocking

摘要

Medicament administration device has a dosage adjuster (9) mounted on the piston rod which is rotated to adjust the dose. An end stop (3c) is mounted at the end of its path and a locking system (8h, 9h) prevents the adjuster from rotating any further and pressing against the stop. An independent claim is included for a reservoir module for the administration device.
